PPV buys for UFC 117

The UFC has some early working PPV numbers for UFC 117, nothing official of course, but they are looking lower than expected.  Sure, with Anderson Silva headlining this past UFC, outstanding numbers weren't expected, but matching him with Chael Sonnen was supposed to boost PPV buys a lot.  Maybe, now that its more and more apparent that Chael's loud loud mouth didn't gain him fans OR PPV buys, he'll try a better strategy =)
